Figure 2

Trajectory analysis of the motion of an object in the AT. (a) The orthogonally positioned and synchronized cameras capture images at the 25 fps rate. 3D trajectories and 2D projection of the trajectories for the distances D = 10 mm, D = 30 mm, and D = 50 mm, between the upper and lower UTs are shown in panels (b), (c), and (d), respectively. The trajectories show that there is an optimized distance between the UT arrays, in which the objects are trapped in 3D more stably.
